Note 1: Equivalent noise level is, according to
ISO 7182 and ISO 9207, calculated as the time--
weighted energy total for noise levels under vari-
ous working conditions with the following time
distribution, 1/3 idle, 1/3 full load, 1/3 full speed.
Note 2: Equivalent vibration level is, according
to ISO 7505, calculated as the time--weighted
energy total for vibration levels under various
working conditions with the following time dis-
tribution: 1/3 idle, 1/3 full load, 1/3 full speed.
